To all whom t may fcozcer'n: y

Be it known that I, JOSEPH F. CHMELIR, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Ventilating-Windows,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification;

My invention relates to that class of windows used in churches and similar large buildings and adapted to be swung into open position to afford ingress and egress of air for proper ventilation. The constructioncomprises two window-receiving casements centrally hinged in line with each other and so connected as to be'capable of swinging in unison and parallel with each other, one of said easements being designed to contain an inner window and the other being designed to contain a storm-window.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a view in elevation of a window constructed according to my invention. Fig. II is a vertical sectional view taken on the line II II, Fig. I. Fig. lIII is an enlarged de-v tail perspective view of one of the pivot-receiving sockets of the inside-window casement. Fig. IV is an enlarged detail view of,

the spring-controlled latch by which the Window-easements are held closed. Fig. V is an enlarged detail perspective View of fragments of the inner-Window easement and the frame in which said easement is mounted and showing one of the hinges on which said casement swings. Fig. VI is a detail perspective view of a fragment of the inner-casement-receiving frame, showing the construction of said frame at the center thereof. Fig. VII is an enlarged horizontal sectional View taken on line VII VII, Fig. II. Fig. VIII is an enlarged detail perspective view of one of the adjustable pivot members to which the outer casement is connected. Fig. IX is an enlarged detail perspective view of one of the controlling-bars connecting the inner and outer easements and by which the pivot member shown in Fig. VIII is carried. Fig. Xis an enlarged horizontal sectional view taken on the line X X, Fig. II. Fig. XI is an en larged detail cross sectional view taken through one side of the outer easement and through one of the guards carried thereby.

I designates' a window-casing.

3 designates a frame mounted within the tical center of the window and the flanges 5 extending downwardly to a position also near the vertical center of the window. The ends of the flanges 4 and 5 do not meet each other, there being a space left between them, as seen in Figs. II and VI, within which the casernent of the inner Window is permitted to swing, as will hereinafter appear.

6 designates an inner easement adapted to receive a window, which may be suitably mounted therein. ably constructed of angle-iron, and it is so mounted within the frame 3 that when closed its lower end will rest against the flanges 4. at the lower portion of the frame 3 and its upper end will rest against the flanges 5 at the upper portion of the frame 3. The casement 6 is permitted to swing on a central pivot between the flanges 4 and 5 of the frame 3, it being mounted on pivots 7, carried by brackets 8, fixed to the casement and seated in socket members 9, mounted on the flange 4 of the frame 3. Vhen the Casement 6 is in closed position, it is retained iirmly within the frame 3 by a latch 10, controlled by a spring l1 and mounted in a housing 13, that is fixed to the easement 6. The latch IOis provided with a beveled point adapted to engage a hook 14, iiXed to the frame 3, and projecting from the latch is an eye I2, adapted to receive a cord, by which the latch may be released from the hook 14 and the Casement 6 swung on its pivots into open position.

l5 designates an outer easement or stormwindow frame, into which a window may be suitably secured. The easement 15 is pivotally supported by a rod I6, that is mounted in sockets 17, carried by brackets 18, that are secured to the window-casing 1.

The easement 6 is prefer- A.

IOO

19 designates guards, preferably of sheet metal, which are riveted or otherwise secured to the lower end of the casementl at its edges and arranged to project therefrom across the interstices between the said frame and the window-casing, so as to exclude the passage of currents of air or moisture through said interstices to the interior of the building to which the window is applied. The upper por* tion of the window-casing is preferably provided at the outside with molding arranged to extend over the edges of the upper end of the outer easement l5, so as to exclude the entrance of air or moisture around said casement.

In order to cause the casements 6 and 15 to swing in unison with each other, I connect them at their lower ends by means which will now be described, the said means being provided for adjustment, so as to be adaptable for service upon windows of varying depths.

2O designates pivot-bars pivoted at 2l (see Figs. II and X) to the easement 6, the said bars being provided with longitudinal slots 23 designates a pivOtreceiving member applied to the pivot-bar 20 and capable of being shifted on said bar according to the requirements necessary to accommodate the application of the parts to window-casements of dierent depths. The pivot receiving member 23 is held to the pivot-bar 2O by a set-screw 25, that passes through the slot- 22 in said bar and is seated in the member 23, so as to clamp said member in any desired position onthe bar 20. The pivot-receiving member 23 is provided with a slot 24, that receives a shifting pivot-bolt 26, which is carried by an arm 27, fixed to the easement l5. The pivot bolt 2G is adapted to operate through the slot 22 of the pivot-bar 2O and is permitted a limited play only by the limited length of the slot 21. Then the easements 6 and 15 are swung on their pivots, the pivotbar 20, while holding the casements together, permits of their swinging freely; but each time that the casements are closed they return to normal vertical positions in alinement with each other by reason of the link connection effected by the pivot-bars 20 and the pivot-receiving members 23, carried thereby. When the casements G and 15 are set in position, the pivot-receiving members 23 are shifted inwardly or outwardly on the bar 20, according to the depth of the window-casing, thereby providing for the proper assemblage of the casements irrespective of the distance they maybe placed from each other.

I claim as my invention- 1. In a Ventilating-window, the combination of a pair of casements independently mounted at their center on pivot-supports, in substantially the same horizontal plane but in different vertical planes, and means Whereby said casements are adjustably connected, substantially as described. y

2. In a ventilating-window, the combination of a pair of casements pivotally mounted at their center in substantially the same horizontal plane, but in different vertical planes, a pivot-bar connected to the bottom of one of said casements, and means whereby the other `easement is adjustably connected to said pivot-bar, substantially as described.

3. In a Ventilating-window, the combination of a pair of casements pivotally mounted at their center in substantially the same hori zontal plane, but in different vertical planes, a pivot-bar connected to the bottom of one of said casements, a slidable pivot-receiving member adjustably secured to said pivot-bar, and a pivot-bolt carried by said second casement at its bottom arranged to operate in said pivot-receiving member, substantially as described.

4. In a ventilating-window, the combination of a pair of pivotallymounted casements, a slotted pivot-bar connected to one of said casements, a slotted pivot-receiving member adjustably secured to said pivot-bar, and a pivot-bolt carried by said second casement adapted to operate in the slot in said pivot-receiving member, substantially as described.
